What are "spectacles"?

Spectacles, also known as eyeglasses, are a type of optical device that is used to improve vision. They consist of a pair of lenses mounted in a frame that sits on the bridge of the nose and ears. The lenses can be made of glass or plastic, and are designed to correct a variety of vision problems such as nearsightedness, farsightedness, astigmatism, and presbyopia. The frames can be made from a range of materials, including plastic, metal, and wood, and come in a variety of shapes and sizes to fit different face shapes and styles. Spectacles are commonly used by people of all ages and can be prescribed by an optometrist or ophthalmologist.
